Erf Then I have no idea what could cause it, sorry :/
Maybe Victor will know...

Not sure why the DOS disks won't boot on your machine, but I just realized I forgot to update the DOS boot disk menu when I switched FreeDOS and LZ-DOS, so the option for LZ-DOS is now booting FreeDOS, and the option for FreeDOS is pointing to the wrong filename. I will release a patch to fix this soon.

I'm downloading version 4.1.1. Thanks for referring to me in giving credits for this discovery.

Maybe it comes a bit late, but I say it nevertheless:

I was able to start UBCD 4.1.0 on that problematic computer, after I have removed that SATA drive from it. After putting the drive back in, it failed to boot, again.

Funny is that thanks to working about this issue, I detected a wrong jumper setting, which made the harddisk function at about 70 degrees Celsius (Fahrenheit 158 degrees). Now I have put the jumper in the proper position, and temperature is back to normal.

All honor for this issue goes to Western Digital, whose disk could work for years at 70 C. It is a Caviar SE 160 GB SATA-II JS1600. Simply put the jumpers as it is written on the cover of the hard-disk and ignore other advanced options. Namely, I use now Opt1 (5-6) and SSE - Spread Spectrum enabled (1-2). Using SSE+PM (jumper at 3-4) makes the drive very hot.

This boils down to: if the BIOS/DOS is able to access the SATA drive, then those boot disks fail to boot.

Normally, that SATA disk is seen as drive 80h (0x80).

The option "ATA device first" does not make any difference, regardless if it is set on "yes" or it is set on "no".

Btw, when configuring GRUB to boot the Knoppix HD installation, the automatically generated list of devices sees SATA HD as 81h and IDE HD as 80h, which is of course wrong; it is the other way arround. That's why I have manually changed device number to 80h for SATA and 81h for IDE, in the devices list of GRUB for Windows.

I consulted the FAQ. There it says that if you want to access SATA drives, you have to set them in BIOS menu as pseudo-IDE drives.

My motherboard does not have pseudo-IDE mode for SATA drives, that's why it gives problems when UBCD tries to access SATA drives.

So, I think this is the big difference between MS-DOS 7.10 or Windows 98 SE boot diskette and FreeDOS and such: MS-DOS can properly access SATA drives in SATA mode, while FreeDOS and such fail to access such drives.

How should I brew my own UBCD version with MS-DOS in place of FreeDOS? I tried to make a 2.88 floppy as indicated, make a MS-DOS system out of it, copy the files from FreeDOS floppy image and put it back to UBCD. Well, it gave an error message that there is not enough place for all the files (of course, FreeDOS system files excluded). The resulting CD is such that this diskette image cannot boot when starting it from UBCD.

Perhaps I should simply put there a Windows 98 SE boot floppy, and boot from it.

I to have the same issue i.e. booting from CD works fine, however booting from USB stick fails with "Invalid OPcode at 0007 ..... ...." error after loading up the FreeDOS OS. The problems is not on all PCs though - desktops seem to work fine (even with SATA drives) where as laptops seem to suffer from the issue. As far as I can tell the issue seems to be how the BIOS is interpreting the USB device (i.e as a hard drive or "other" device). The questions is, is it the BIOS that is at fault here (by the way the BIOS is uptodate) or is it todo with the way FreeDOS is seeing the USB device on certasin BIOS's. Perhasp the USB memeory sticks are being presented differently under different BIOSs?

Perhaps a different approach may be worth a try e.g loading all the freedos stuff into a vritual RAM drive and loading it from theret?

I have the same problem. I have UBCD v 4.1.1 installed on a USB drive, and I'm using it on a Thinkpad T41. None of the versions of DOS boot (I tried FreeDOS, LZ-DOS, and OpenDOS). FreeDOS gives the message:
